Neisseria gonorrhoeae by restriction fragment length polymorphisms
Objective-To characterise Neisseria gonorrhoeae isolates by restriction fragment length polymorphisms (RFLPs) in ribosomal RNA genes. Design-Generation of RFLP patterns by HincII restriction of rRNA genes followed by hybridisation with a nonradioactive labelled broad spectrum 16 + 23S rRNA gene probe. This typing method was developed and compared with MAb based serotyping. Specimens-Forty three...
متن کاملClassification of Histoplasma capsulatum isolates by restriction fragment polymorphisms.
Twenty isolates of the dimorphic, pathogenic fungus Histoplasma capsulatum were divided into three classes based on comparisons of restriction enzyme digests of their mitochondrial DNA and rDNA. The majority of isolates, including most North American strains and the African H. capsulatum var. duboisii variants, belong to class 2. Isolates from Central America and South America make up class 3. ...
متن کاملMan Using Restriction Fragment Length Polymorphisms
We describe a new basis for the construction of a genetic linkage map of the human genome. The basic principle of the mapping scheme is to develop, by recombinant DNA techniques, random single-copy DNA probes capable of detecting DNA sequence polymorphisms, when hybridized to restriction digests of an individual's DNA. Each of these probes will define a locus. Loci can be expanded or contracted...
متن کاملHeterogeneity among Dermatophilus congolensis isolates demonstrated by restriction fragment length polymorphisms.
There is evidence of antigenic diversity and of differences in virulence in Dermatophilus congolensis. For the understanding of the epidemiology of dermatophilosis it is important to distinguish between strains of the organism. Twenty field isolates from cattle in Chad and Cameroon, and an American reference strain, have been examined on restriction fragment length polymorphisms. After restrict...
متن کاملCharacterization of microbial diversity by determining terminal restriction fragment length polymorphisms of genes encoding 16S rRNA.
A quantitative molecular technique was developed for rapid analysis of microbial community diversity in various environments. The technique employed PCR in which one of the two primers used was fluorescently labeled at the 5' end and was used to amplify a selected region of bacterial genes encoding 16S rRNA from total community DNA. The PCR product was digested with restriction enzymes, and the...
